Variations in Bulk Density and Moisture Content Within Two New Jersey Coastal Plain Soils, Lakeland and Lakehurst Sands
1964
Reigner, Irvin C. | Phillips, John J.
To determine how manipulation of vegetative cover affects soil-moisture storage, 8 plots were laid out in a 50-acre block on the Coastal Plain of New Jersey, 4 on Lakeland sand and 4 on Lakehurst sand. Each plot, about 1/100 acre in size, was subdivided into 3 subplots, each of which was sampled gravimetrically 42 times over a period of 3 growing seasons. A relationship between bulk density and soil depth plus stone content was developed. From this, bulk density was estimated for each sample in five 1-foot layers. Moisture content by weight for each 1-foot layer was converted to moisture content by volume by applying the respective estimated bulk densities. Variations within and between the relatively close-spaced plots are presented for estimated bulk density and moisture content by voulme for each of the 1-foot layers.
